    Default Nutrient deficiency?

    Evening troops, I was wondering if someone would be able to help me. So I am growing using 4 pot rdwc system and I am IMG_3537.jpgIMG_3538.jpgcurrently coming to the end of week 4 and I noticed some spots on two of the leaves, and only on one of the plants. Iím guessing itís a deficiency? The other question I was going to ask the forum was when I set my EC to say 0.7 and over the course of a few days the EC drops to 0.5. How much do I let it drop by before I add more nutrients to the system and also how do I figure out how much more to add? As always guys any help is greatly appreciated

    What are you feeding them?
    What's the EC of your water before you added neuts?
    And show us a pic of the whole plant.

    I'm no expert but I had that in a previous grow and calmag sorted it.

    Looks like calcium to me. Other than that I cannot help. DWC is not where I shine. Cheers.

    It looks minimal on older leaves as long as your ph drifts up over 6 as well id say it's nothing to worry about.
    New growth looks good and is say your neuts are spot on.

    Someone with more experience the me will come along soon and give you their oppinon
    I'm only an apprentice yet.
